Step-by-step explanation:

Ok so I copy and pasted this try to squish that together lol

simplified, it would be: -4x^5-9x^4+15x+1

Step-by-step explanation:

idk

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
